The speed of light in a material depends on:
Correct answer: A. Refractive index
- A. Refractive index
- B. Frequency
- C. Amplitude
- D. All
Explanation
A is the right option because The speed of light in a material depends primarily on its refractive index, which is a measure of how much the speed of light is reduced when it enters the material compared to its speed in a vacuum.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
